Patent ES-229012-A1 (ES)
Title: Process and apparatus for the manufacture of phosphoric acid
Inventor: MACQ DR ANDRE
IPC: C01B25/22
Filed: 1956-06-07
Abstract: <PICT:0831970/III/1> Phosphoric acid is manufactured continuously by separately introducing natural phosphate and sulphuric acid into the reaction mixture in a single reaction zone, establishing a toroidal current in the reaction medium about a vertical axis, establishing a circularly-moving current extending laterally about a vertical axis in another portion of the reaction medium but overlapping the toroidal current so that a portion of the toroidal current commingles with the circularly-moving current. Phosphate, which may be accompanied by phosphoric acid and wash waters from the filters, is introduced into acid-resistant tank 1 into truncated conical shield 2 mounted around rotating impeller 3 with the upper edge of the shield below the liquid level, which sets up a current descending in the shield in convering-diverging confinement and rising outside. Conical projection 7 and arcuate barrier 8 assist in dispersing the liquid from the cone in the reaction medium. H2SO4 from 11 is dispersed throughout the reaction medium by agitators 4, 5, 6, equipped with vanes. The agitators withdraw liquid from the current rising round shield 2 into the reaction medium and return acid liquid to the rising current, so that a vertical current meets a horizontal current. The tank has current breaking ribs 9, and reaction medium is continuously withdrawn to filters for removing CaSO4 through an outlet from the toroidal current.

Title: Centering apparatus for match plates arranged at a match plate support for molding machines
IPC: B22C7/04
Filed: 1968-11-18
Abstract: A heated pattern plate 7, having patterns 7.7 attached to it, has two sides at right angles to one another 7.1, 7.2 (Fig. 2) accurately machined to form abutment surfaces which abut accurately machined abutment surfaces 1.11, 1.21 of a pattern plate carrier 1 (of a foundry moulding machine) to locate the pattern plate within its carrier. The abutment surfaces are forced together by a fluid expanded elastic tube 8 nested within a groove 1.41 extending around those two walls 1.3, 1.4 without abutment surfaces, of the pattern plate carrier. Alternatively, pistons and cylinders (not shown) mounted on the walls 1.3 and 1.4 are used to force the abutment surfaces together. Four bolts 10 pass through the pattern plate assembly 4, 5, 6, 7 (which is vertically movable on the bolts) and are anchored to the base 1.5 of the carrier 1. The lower surfaces of the bolt heads 10.1 are exactly level with the upper surface 1.61 of the carrier. The part 4.2 has large bores 4.3 with pistons 4.6 mounted in them, and the bores 4.3 are interconnected by passages 4.4 leading to a pressurized fluid supply by a connection 12. The pistons 4.6 act against the base 1.5 forcing the part 4.2 upwards and the pattern plate against the bolt head 10.1 thereby locating it vertically. A further embodiment (not shown) includes four separate rectangular pattern plates within a rectangular carrier, all located within the holder by an expandable elastic tube in a groove around the four inner walls of the carrier.

Arm 88 is secured to rod 90 so that its position is controlled by engagement of crank 102 with fixed cam 114 so that as the carrier moves clockwise it is raised and lowered to enter the galvanizing tank 14 and then raised and lowered to leave the tank. When the carrier reaches the centrifuge 16 the operator shown is able to speed the process by pulling towards him the arm 52 relative to arm 50 and the carrier is then lowered into the centrifuge and lifted out of it to be delivered at the discharge point 18. Mechanical aid for operator when centrifuging, (Fig. 3).-When the arm 52 carrying carrier 66 reaches the centrifuging station the crank 112 engages a cam 148 which is secured to and operated by fluid cylinder 140 so that by the raising of cam 148 the operator controls the lowering under gravity of the carrier into the centrifuge and by the lowering of cam 148 lifts it out, the operation of cylinder 140 being footcontrolled. Alternatively the lifting of the carriers 60 up and down may be affected by fluid cylinders positioned on the arms 50 and 52 which constitute the rotary conveyer.

Title: Pneumatic conveying apparatus
IPC: B65G53/46
Filed: 1971-04-10
Abstract: A pneumatic conveying apparatus which includes a housing having an inlet for material to be conveyed and an outlet. A tubular member is slideably mounted in the housing and serves as a conduit for conveying the material from the inlet to the outlet. A gas pressure operated piston-cylinder arrangement is used to reciprocate the tubular member. As the tubular member reciprocates, a reduced pressure zone is created at the inlet to drawing material into the housing and charge the apparatus. Air exhausted from the piston-cylinder arrangement is used to convey the material. Suitable valving is provided to conduct gas under elevated pressure to opposite sides of the piston to reciprocate the piston and tubular member and direct most of the gas exhausted from the piston-cylinder arrangement to the outlet of the pump to convey the material. Some of the gas exhausted from the piston-cylinder is used to convey the material through the apparatus.

Title: Apparatus and method for doffing wound packages and donning empty cores
IPC: B65H67/04
Filed: 1971-04-30
Abstract: Apparatus and method for doffing wound packages of strand materials and for donning empty cores for resumption of winding, while avoiding interruption of the movement of strand material to be wound, if desired. As applied to a textile yarn texturing machine, a core supporting arm is displaced from a winding position to a doffing position and a wound package is doffed from the arm. Yarn being textured is severed, to separate a doffed package therefrom, and an empty core is donned on the arm as the same returns to a winding position. During doffing and donning, a running end of the yarn being textured is taken up and is subsequently severed to form a free end to be wound about the donned empty core.

Title: Jet powered watercraft
IPC: B63H11/08
Filed: 1975-09-05
Abstract: A jet powered watercraft of motorcycle-like configuration. Longitudinally aligned front and rear skis are located in spaced relation below a hull and operate to hydrodynamically lift the watercraft to a cruise position by relative water flow upon the undersides of the skis. The rear ski and a jet pump are secured as an integral unit to an engine. The rear ski includes an opening through which water passes to the jet pump, and further includes channels on either side of the opening to collect and carry away entrained air. The engine is located in the hull and is cooled by water supplied by the jet pump which it drives. The front ski is rotatable for steering and is resiliently extensible for stability in turning. The center of buoyancy of the watercraft is above its center of gravity so that the craft is self-righting. The exhaust and cooling systems are arranged to eliminate flooding despite location of portions of the engine below water when the craft is at rest. The jet pump discharge nozzle is completely out of the water in the cruise position of the craft for maximum thrust.

Patent ES-453716-A1 (ES)
Title: Method and apparatus for reducing lateral force variations and overturning moment variations in pneumatic tires
IPC: B29C67/00
Filed: 1976-11-26
Abstract: A method and apparatus for reducing lateral force variations and overturning moment variations in pneumatic tires by detecting the magnitude, direction and location of such variations and alternatingly grinding off opposite portions of the two shoulders of the tire tread. A tire is mounted on a test rim, inflated to operating pressure, and rotated under a normal service load against a loading drum. Force variations in the lateral and radial directions are detected and measured by load cells operatively associated with the drum axle and located at opposite ends of the axle. The sum of the lateral force variation forces or the difference of the radial force variation forces measured by the load cells provides a voltage level signal representative of the direction, magnitude and location of the lateral force variation and the overturning moment variation. The phase angle of this signal is ascertained to determine the location on the tire of these variations. Where these variations exceed a preset level, they are reduced by alternatingly grinding a zone of one shoulder of the tire tread and the opposite zone of the other shoulder of the tire tread in response to the phase angle of the variation signals. Reduction of lateral force variations by this method also reduces radial force variation.
